The systematic recording of spontaneous electrodermal activity (EDA) on 23 normal subjects during 5 15-min sessions and the self-rating of anxious and/or depressive moods (Q-sort forced choice) shows a positive linear relationship between spontaneous EDA and anxious mood despite a low covariation between thoše two variables.
